IC693DNM200 DeviceNet Master Module | 5V DC 450mA Single-Slot GE

GE Fanuc Series 90-30 IC693DNM200 Overview

The GE Fanuc IC693DNM200 is a high-performance, single-slot DeviceNet Master Module engineered for the legacy Series 90-30 and modern PACSystems RX3i Programmable Logic Controller (PLC) architectures. Manufactured formerly by GE Fanuc and now supported under Emerson Automation, this communication interface serves as a centralized industrial network hub, allowing host controllers to seamlessly exchange I/O mapping data with distributed field devices. The hardware design features a compact, single-slot form factor with a lightweight profile of 0.5 kg (approximately 1.1 lbs), optimizing physical space utilization across internal rack layouts. Functioning via an internal logic current draw of 450 milliamps at 5.0 Volts DC, this module delivers robust network bridging capabilities, acting simultaneously in dual-mode configuration as both a Master node and a Slave device to facilitate localized processing and factory-wide automation synchronization.

Core Network Features & Data Architecture

DeviceNet Capacity and Protocol Support

The IC693DNM200 is built to establish stable network structures, accommodating up to 63 independent DeviceNet slave units. It supports standard protocol transmission speeds, operating at 125K, 250K, and 500K Baud rates depending on overall bus distance and infrastructure needs. For advanced industrial communication, the module integrates extensive messaging toolsets, including explicit messaging routines, Unconnected Message Manager (UCMM) architectures, and 1 dedicated proxy connection per assigned slave terminal.

Data Transmission Limits and I/O Connections

Designed for substantial diagnostic data logging and dense field array management, the master module supports a large aggregate bandwidth. It is capable of transferring up to 255 Bytes of input data and 255 Bytes of output data per individual slave unit, with an absolute maximum data transfer throughput to the host Master reaching 3,972 Input Bytes and 3,972 Output Bytes. A total of 126 concurrent I/O connections can be sustained across the network bus, allowing up to 2 distinct I/O station links to be established for each connected field device.

Configurable Transfer Connections & Fault Logic

To optimize communication latency and network traffic based on physical machinery constraints, data synchronization can be structured into Poll, Strobe, Cyclic, or Change-of-State (COS) I/O configurations. Furthermore, the firmware incorporates a user-configurable fault behavior routine, allowing automated system engineers to establish precise, safe fallback reactions and machine hold states in the event of sudden bus communication timeouts or network line breaks.

Installation, Hardware Routing, & Electrical Guidelines

Mechanical Layout and Rack Placement Safety

The IC693DNM200 single-slot communication card is designed to sit exclusively within the main system rack of a Series 90-30 or PACSystems RX3i assembly. To ensure proper addressing and electrical line integrity, the module can be placed into any standard slot on the main baseplate, with the strict exception of slots 0 and 1, which are reserved for system power supplies and CPU controllers. Please note that this communication module does not support integration into remote or expansion racks. Prior to sliding the card into the backplane, confirm the power supply is off to protect the communication chipsets from damage.

Channel Groupings and Output Current Limits

The module features 32 onboard output points grouped into sets of four, with each group covering 8 distinct output points. When wiring the external 12-24V DC positive logic field array, engineers must follow specific electrical thresholds to avoid overheating the traces. While each separate point can handle a continuous current load of up to 0.5 Amps, the absolute collective limit per group must not surpass 4.0 Amps. Additionally, ensure the continuous current passing through any single group common pin does not exceed 3.0 Amps.

Firmware Upgrades and Diagnostic Service Routing

The front faceplate of the IC693DNM200 houses a single DeviceNet plug-in terminal alongside an isolated 9-pin D-shell female RS-232 service port. This serial line serves as a local interface for executing diagnostic checks and applying system patches. Because the device is built with upgradeable flash memory, field technicians can download the latest firmware iterations and security patches directly via the RS-232 port, avoiding the need for physical chip swaps during routine system maintenance.

Frequently Asked Questions (FAQs)

Q1: Can I install the IC693DNM200 module into an expansion rack to save space on my main PLC baseplate?
A1: No. The IC693DNM200 must be installed directly on the main rack of a Series 90-30 or PACSystems RX3i setup. The internal architecture of the module requires direct, high-speed backplane mapping that is not supported through the bus cables of expansion or remote chassis racks.

Q2: What are the specific power limitations regarding the 32 integrated output points?
A2: Each point supports a continuous current of 0.5 Amps. However, the outputs are clustered into groups of 8 points. The total combined draw for an entire group must not exceed 4.0 Amps, and the return current routed through any individual group common pin must stay below 3.0 Amps to prevent thermal damage.

Q3: What role does the dual-mode master/slave operational feature play in field applications?
A3: Dual-mode operation allows the IC693DNM200 to act simultaneously as a Master node and a Slave device on the same network line. This enables the module to poll localized field sensors (Master mode) while concurrently feeding grouped status metrics upward to a larger supervisory factory controller (Slave mode).
